FHFA Announces Deemed-Issuance Ratio for 2020


​Washington, D.C. – The Federal Housing Finance Agency (FHFA) today announced the deemed-issuance ratio for the 2020 calendar year in accordance with Internal Revenue Service (IRS) guidelines on the trading of the Uniform Mortgage-Backed Security (UMBS). 

The IRS Revenue Procedure 2018-54 provides guidance on section 817(h) of the Internal Revenue Code diversification requirements for variable annuity, endowment, and life insurance contracts, as compliance with those requirements is affected by the implementation of the Single Security Initiative and trading in UMBS.

Revenue Procedure 2018-54 calls for FHFA to determine a deemed-issuance ratio for each calendar year based on the ratio of TBA-eligible securities issued by Fannie Mae and Freddie Mac during the 24-month period ending October 31 of the preceding year.

The IRS procedure provides that the ratio may be rounded as long as the rounded ratio is further from 50-50 than the actual observed data. Therefore, the deemed-issuance ratio for the 2020 calendar year is 60% Fannie Mae and 40% Freddie Mac.
